Esthetic impact of malocclusions in the anterior segment on children in the mixed dentition

To assess the esthetic subjective effect of malocclusions in the anterior segment on children in the mixed dentition. A cross-sectional study was carried out with a population-based sample of 787 children aged 8-10years in the late mixed dentition (n=787). Orthodontic Aesthetic Subjective Impact Score determined the esthetic subjective effect. For assessing the malocclusions in the anterior segment (anterior crowding, anterior spacing, diastema, anterior open bite, and anterior maxillary overjet), the following Dental Aesthetic Index criteria were used. Sex, family income, and education level were used as control variables. The variables were analyzed using a simple logistic regression model, estimating crude odds ratios. The variables with P<0.20 in the simple analyses were tested in multiple regression models, estimating adjusted odds ratios with the respective 95% confidence intervals. Increased overjet was 1.54 (95% CI: 1.08-2.17) times more likely to cause greater estheticconcern (P<0.05), especially in girls (P<0.05). Increased overjet negatively affected children's esthetic self-perception in the mixed dentition.

Impact of anterior occlusal conditions in the mixed dentition on oral health-related quality-of-life item levels.

To evaluate the impact of anterior occlusal conditions in the mixed dentition on item-level analysis of oral health-related quality of life (OHRQoL). A population-based cross-sectional study of 787 children aged 8 to 10 years was conducted. The Child Perceptions Questionnaire (CPQ8-10) was used to evaluate OHRQoL, and the analysis of item levels was performed on CPQ8-10 domains. Anterior occlusal characteristics were diagnosed according to the Dental Aesthetic Index criteria. Individual analyses were performed relating the outcome as independent variables. The variables with P < .20 in the individual analyses were tested in multiple logistic regression models, and those with P < .10 remained in the model. The adjusted odds ratio (OR) was estimated with a 95% confidence interval (CI). No associations were found with regard to anterior occlusal characteristics (P < .001) after the variables of the previous determinants were adjusted for multivariate analysis. However, the following variables were significantly associated with negative impact on OHRQoL item levels: sex, in oral symptoms (OR = 1.42; CI, 1.07-1.89) and emotional well-being (OR = 1.34; CI, 1.00-1.79); race, in oral symptoms (OR = 1.48; CI, 1.10-1.98), emotional well-being (OR = 1.54; CI, 1.14-2.06), and social well-being (OR = 1.34; CI, 1.00-1.80); and family income in functional limitation (OR = 1.46; CI, 1.06-2.02), emotional well-being (OR = 1.71; CI, 1.21-2.42), and social well-being (OR = 1.59; CI, 1.14-2.21). Anterior occlusal conditions did not affect the levels of OHRQoL items.

Prevalence of malocclusion among 15-year-old school children using dental aesthetic index in Nalgonda district, Andhra Pradesh, India: A cross-sectional study

Background: The available literature on the prevalence of malocclusion among school children in endemic fluoride areas in India is scanty. Objectives: The objective was to assess the prevalence of malocclusion using dental aesthetic index (DAI) and its association with gender, area of residence, and fluoride concentration among 15-year-old school children. Materials and Methods: This cross-sectional study was conducted among 15-year-old school children in the rural and urban areas of Nalgonda district, Andhra Pradesh, India. Two-stage cluster sampling was used for selecting the eligible children. Six out of 59 mandals in Nalgonda district were selected by simple random sampling technique. All the secondary schools in rural and urban areas of these mandals were listed and subsequently, four schools from each of these mandals were selected using random sampling. All eligible children aged 15 years were selected and assessed for malocclusion using Dentofacial anomalies with criteria of DAI by three trained and calibrated dentists. The DAI in relation to gender and area of residence were compared and analyzed using SPSS 16. Student's t-test and one-way ANOVA were used for comparing the mean values between groups. The qualitative data were analyzed using the Chi-square test. Results: A total of 1484 children was examined. The prevalence of malocclusion was 17.9%. The prevalence was significantly higher (P = 0.001) among females (23.6%) compared to males (13%). The prevalence was significantly higher (P = 0.001) in urban areas (22.2%) compared to rural areas (15%). The prevalence was significantly less (P = 0.001) in optimal (13%) and above optimal areas (8%) compared to below optimal areas (23%). Conclusion: The prevalence and severity of malocclusion were more among females, urban, and below optimal fluoride areas.

Evaluation of Orthodontic Treatment Needs Using the Dental Aesthetic Index in Iranian Students

BackgroundIn the contemporary orthodontics, the number of people who demand orthodontic treatment to improve their psychosocial issues related to facial esthetic is constantly increasing. Even in treatment plans, appearance and esthetic gain more attention.ObjectivesThe purpose of this study was to determine the need for orthodontic treatment on the basis of the dental aesthetic index (DAI) in the Iranian students of Ahvaz city.Material and MethodsThis cross sectional study was performed on 900 students aged between 11 - 14 years (450 boys, 450 girls). Schools were selected based on random cluster sampling from different parts of the city. Students\\ who had or were having orthodontic treatment including those on interceptive orthodontics, were excluded from the study. Two questionnaires were used; the first one included different DAI criteria, and the second one included two questions about orthodontic treatment need and satisfaction of personal dental appearance. The results were analyzed by Chi-Square and T test.ResultsIn 70.9% of the students, DAI score was 13 - 25, 19.2% of the samples had a DAI score of 26 - 30, the DAI score of 7.8% was 31 - 35, and in 2.1% the DAI score was greater than 35. The association between the DAI score and sex was not statistically significant (P = 0.778). In relation to orthodontic treatment need, 44.8% of students answered positively, while in 55.2% the answer was negative. In relation to satisfaction with appearance, 21% of the students were satisfied with their appearance, 59% were relatively satisfied, and 19.9% were not satisfied with their appearance. The association between DAI score and the need for orthodontic treatment and satisfaction of dental appearance was significant (P = 0.000).ConclusionIn comparison to other studies, the students in Iran (Ahvaz) have a better dental appearance and less need for orthodontic treatment. Significantly positive correlations were found between the DAI and satisfaction of dental appearance, orthodontic treatment need and student’s perception.

Malocclusion status among 15 years old adolescents in relation to fluoride concentration and area of residence

To compare the overall dental aesthetic index scores between rural and urban areas, males and females, and to correlate dental aesthetic index score with fluoride concentration in drinking water. The study was cross sectional and conducted among 15 year old adolescents in the rural and urban areas of Nalgonda district, Andhra Pradesh, India (an endemic fluoride belt). Six out of 59 mandals in Nalgonda district were first selected by simple random sampling technique. Then 24 secondary schools were selected from these six selected mandals. All eligible grade X children from these sixteen rural and eight urban schools, having different fluoride concentrations in drinking water, selected by simple random sampling, were considered for the study. Dentofacial anomalies with criteria of dental aesthetic index were used for assessing malocclusion. The information on the dietary habits, orthodontic treatment history, parafunctional habits, continuous residence etc., was collected using a pre-designed questionnaire. The examination was carried out by three trained and calibrated dentists. The Dental Aesthetic Index (DAI) scores, in areas with below optimal, optimal and above optimal fluoride concentrations, between urban and rural areas were compared and analyzed using SPSS windows version 16. The mean DAI scores, for the rural and urban population were 21.37 ± 5.845 (mean ± SD) and 22.26 ± 6.115, for males and females, it was 20.86 ± 5.100 and 22.70 ± 6.713 respectively. The mean DAI scores in areas with below optimal, optimal and above optimal fluoride concentration were 23.42 ± 7.205 (mean ± SD), 20.85 ± 4.658 and 19.93 ± 4.312 respectively. The prevalence and severity of malocclusion was more in urban than rural areas, more among females than males, and it decreased with increasing concentration of fluoride in drinking water.

Validity and reliability of the Brazilian version of the psychosocial impact of dental aesthetics questionnaire

Oral health-related quality of life (OHRQoL) is an important aspect of health outcomes and its assessment should be made using validated instruments. The psychosocial impact of dental aesthetics questionnaire (PIDAQ) is an OHRQoL instrument that assesses the psychosocial impact of dental aesthetics was developed and validated for use on young adults. The aim of the present study was to assess the reliability, validity, and applicability of the PIDAQ for young adults in Brazil. After translation and cross-cultural adaptation, the questionnaire was completed by 245 individuals (124 males and 121 females) aged 18-30 years from the city of Belo Horizonte, Brazil. In order to test discriminant validity, the subjects were examined for the presence or absence of malocclusion based on the dental aesthetic index criteria. Dental examinations were carried out by a previously calibrated examiner [weighted kappa = 0.64-1.00, intraclass correlation coefficient (ICC) = 0.78-1.00]. Internal consistency measured by Cronbach's alpha of the subscales was between 0.75 and 0.91 and test-retest reliability was assessed using the ICC, which ranged from 0.89 to 0.99 for dental self-confidence and social impact, thereby revealing satisfactory reliability. Discriminant validity revealed that subjects without malocclusion had different PIDAQ scores when compared with those with malocclusion. The results suggest that the Brazilian version of the PIDAQ has satisfactory psychometric properties and is thus applicable to young adults in Brazil. Further research is needed to assess these properties in population studies.
